Chicago is served by two main airports with distinct roles. O'Hare International (ORD) is the city's primary international hub, handling many transcontinental and global carriers—United, American, and numerous international airlines—so fares can be competitive on major routes but vary by carrier and season. It sits about 17 miles northwest of downtown; public transit via the CTA Blue Line typically takes 40–50 minutes, while taxis or rideshares are commonly 30–60 minutes depending on traffic, with fares and surge pricing varying. Midway (MDW) is a smaller, more domestic- and low-cost-carrier–oriented airport that many travelers perceive as budget-friendly and closer to the city, roughly 10 miles southwest; an Orange Line ride to downtown usually takes 25–35 minutes, and road transfers are often 25–45 minutes. O'Hare offers extensive international connectivity and many amenities but can be busy and spread out; Midway can be quicker to navigate and parking may be simpler, though it has fewer long-haul options.

The airport sits roughly 10–15 miles (16–24 km) south of downtown Atlanta; MARTA rail connects the domestic terminal to the city center in about 15–20 minutes with fares usually in the low single digits, while taxis and rideshares often take 20–40 minutes depending on traffic and can be pricier.
